Delaware Investments Closed-End Municipal Bond Funds
April 12, 2011

Performance preview

The fiscal year ended March 31, 2011 was generally volatile for the Funds (and for investors in tax-exempt debt in general). Municipal bonds were under considerable selling pressure during the later parts of the fiscal year, driven primarily by fears about the credit worthiness of the municipal bond market, as well as technical developments that affected bond supply. Despite a fiscal year that ended in a flurry of headwinds, municipal bonds posted a cumulative gain of slightly more than 1.5% for the period (as measured by the Barclays Capital Municipal Bond Index).

National economic environment

During the fiscal year, the U.S. economy continued to emerge from its biggest downturn in seven decades, albeit relatively slowly. As the Funds’ fiscal year got under way, U.S. economic growth softened, with gross domestic product (a measure of the economy’s production of goods and services) slipping from an annualized rate of 3.7% in the first quarter of 2010 to just 1.7% in the second quarter. The grim economic situation was reflected in the national unemployment rate, which stood at 9.7% at the start of the fiscal year.

Several factors contributed to sluggish economic performance, among them:

Many investors focused their attention on the high levels of sovereign debt across the developed world (and particularly in Greece), fearing that reductions in government spending could exacerbate declining economic growth.
The U.S. housing market’s glut of supply continued to weigh on home prices in many parts of the country.
State and local governments, whose spending makes up a sizeable component of GDP, largely cut back expenditures to meet big budget shortfalls.

GDP data moderately improved as the fiscal year went on, with the economy growing at an annual rate of 2.6% in the third quarter of 2010 and 2.8% in the final three months of that year. The employment picture, while still generally challenging, began to improve as well, finishing the Funds’ fiscal year at 8.9%.

Municipal market trends

For the first two quarters of the Funds’ fiscal year, the municipal bond market enjoyed relatively strong performance, echoing the positive trends of 2009. The municipal bond market benefited from several factors, including:

Low inflation and declining interest rates provided a generally favorable climate for fixed-income securities.
The popular Build America Bond (BAB) program continued to divert supply away from the traditional tax-exempt bond market and toward the taxable bond market.
In this environment of reduced supply of tax-exempt securities, demand remained strong, especially for lower-rated, higher-yielding issues.

In November 2010, conditions in the tax-exempt bond market deteriorated suddenly, as many investors became increasingly concerned about the potential for inflation to put downward pressure on bond prices. Concerns were heightened by several developments, including the Federal Reserve’s announcement that it would engage in another round of quantitative easing, in which it plans to purchase $600 billion of Treasury securities, in order to further spur economic growth.

Meanwhile, several other events inhibited the municipal bond market:

With the BAB program facing expiration at the end of 2010, many investors realized that supply of tax-exempt bonds could potentially increase markedly.
Negative sentiment grew about the fiscal health of state and local governments.

Portfolio management review

Delaware Investments Closed-End Municipal Bond Funds

Significant gains in the number of Republican seats in Congress led many investors to envision a less friendly environment for federal aid to help states manage their budget challenges.
An extension of Bush-era tax cuts led some investors to view the tax advantage of municipal bonds less favorably.

This confluence of factors precipitated dramatic investment outflows from municipal bond funds in the final months of 2010 and early 2011, reversing the tremendous inflows seen during the market’s run-up in much of 2010. In turn, these outflows put downward pressure on municipal bond prices.

Fund positioning

When the Funds’ fiscal year began, we maintained a modest emphasis on lower-rated, longer-dated securities, using our research capabilities to help identify those securities we believed offered good value relative to their risk. This approach generally worked well; within each of the Funds, these types of securities generally added to performance.

Unfortunately, this approach hampered the Funds’ returns relative to their benchmark index when market conditions deteriorated in the final months of the fiscal year. As investors’ confidence in the tax-exempt bond market generally waned, securities with heightened credit risk (such as lower-rated bonds) or interest-rate risk (namely, bonds with longer maturity dates) underperformed their higher-rated, shorter-dated counterparts.

As the Funds’ fiscal year came to a close, we faced the need to make a decision about current market conditions — whether to treat them as a passing storm or as a fundamental change that warranted a shift in approach. We concluded that the increased volatility in the municipal bond environment at least required us to position the Funds somewhat more conservatively. This resulted in an increased focus on intermediate-maturity bonds with higher credit ratings, and a reduction of exposure to longer-dated, lower-rated bonds where appropriate.

Performance effects

Our conservative positioning was consistent with our overall philosophy of managing the Funds with an emphasis on preserving principal. We were willing to be somewhat more conservative than some other municipal bond managers (perhaps sacrificing a bit of performance potential) in an attempt to avoid greater losses during particularly difficult market downturns.

On an individual security basis, the Funds often saw good results from the types of bonds that outperformed for the fiscal year; namely, bonds with shorter maturities and relatively higher credit ratings. Within Delaware Investments Arizona Municipal Income Fund, Inc., for instance, bonds with relatively shorter maturities led the way, including bonds issued by the University of Arizona (maturing in 2018) as well as housing bonds issued by the City of Phoenix (maturing in 2020).

Leading contributors also included prerefunded bonds, which are very high-quality, short-duration bonds. (When a bond is prerefunded, the issuer has secured the bond’s principal value by holding some type of risk-free asset — typically Treasurys — in an escrow account). Within Delaware Investments Colorado Municipal Income Fund, Inc., prerefunded bonds issued by the University of Denver and by the Denver Convention Center Hotel Authority were among the Fund’s leading contributors.

Similar to the Colorado Fund, Delaware Investments Minnesota Municipal Income Fund II, Inc. benefited from holdings in prerefunded bonds that raised money for civic projects, as bonds for the St. Paul civic center were among its strongest contributors.

Leading contributors within Delaware Investments National Municipal Income Fund included bonds issued in New York that were backed by American Airlines (in an arrangement commonly known as an industrial development revenue bond) and an energy bond issued in Iowa by the state’s Authority for Interstate Power. Both bonds advanced by more than 5%.

Across all four Funds, the weakest contributors to overall return included bonds issued by the Commonwealth of Puerto Rico. These bonds, which are widely held and are highly liquid, came under tremendous selling pressure during the last half of the Funds’ fiscal year. In a sense, the characteristics that make Puerto Rico bonds desirable were the very characteristics that worked against them: They became the instrument of choice for municipal bond investors seeking to raise cash. (This was particularly true for mutual fund managers who needed to satisfy investor redemptions.) The resulting decline in bond prices was widespread and difficult to control, and it was a good example of the dislocation that municipal markets were suffering through.

As in prior reporting periods, we continued to follow our basic investment philosophy and management approach. We believe successful municipal bond investing requires rigorous credit analysis. In our opinion, there is no substitute for thorough credit research. On a bond-by-bond basis, we scrutinize each security we include in the Funds to help ensure our comfort level with its financial position and to feel confident that, in our view, any risks are more than offset by the potential income provided by the bond.

1 Total investment return is calculated assuming a purchase of common stock on the opening of the first day and a sale on the closing of the last day of each period reported. Dividends and distributions, if any, are assumed for the purposes of this calculation to be reinvested at prices obtained under the Fund’s dividend reinvestment plan. Generally, total investment return based on net asset value will be higher than total investment return based on market value in periods where there is an increase in the discount or a decrease in the premium of the market value to the net asset value from the beginning to the end of such periods. Conversely, total investment return based on net asset value will be lower than total investment return based on market value in periods where there is a decrease in the discount or an increase in the premium of the market value to the net asset value from the beginning to the end of such periods.

2 Ratios do not reflect the effect of dividend payments to preferred shareholders, if applicable.

3 Ratio reflects total net investment income less dividends paid to preferred shareholders, if applicable, divided by average net assets applicable to common shareholders.

4 In 2008, the Fund redeemed all of its preferred shares at par plus accumulated dividends amounting to $25,024,395.

Delaware Investments Closed-End Municipal Bond Funds

March 31, 2011

Delaware Investments Arizona Municipal Income Fund, Inc. (Arizona Municipal Fund), Delaware Investments Colorado Municipal Income Fund, Inc. (Colorado Municipal Fund) and Delaware Investments Minnesota Municipal Income Fund II, Inc. (Minnesota Municipal Fund II) are organized as Minnesota corporations and Delaware Investments National Municipal Income Fund (National Municipal Fund) is organized as a Massachusetts business trust (each referred to as a Fund and collectively as the Funds). Arizona Municipal Fund, Colorado Municipal Fund, Minnesota Municipal Fund II and National Municipal Fund are considered diversified closed-end management investment companies under the Investment Company Act of 1940, as amended. The Funds’ shares trade on the NYSE Amex Equities, the successor to the American Stock Exchange.

The investment objective of each Fund is to provide high current income exempt from federal income tax and from state personal income tax, if any, consistent with the preservation of capital. Each Fund, except National Municipal Income Fund will seek to achieve its investment objective by investing substantially all of its net assets in investment grade, tax-exempt municipal obligations of its respective state.

1. Significant Accounting Policies

The following accounting policies are in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and are consistently followed by the Funds.

Security Valuation — Debt securities are valued by an independent pricing service or broker. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Short-term debt securities are valued at market value. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of each Fund’s Board of Directors/Trustees (each a Board, and collectively, the Boards). In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security.

Federal Income Taxes — No provision for federal income taxes has been made as each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Funds evaluate tax positions taken or expected to be taken in the course of preparing the Funds’ tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Funds’ tax positions taken on federal income tax returns for all open tax years (March 31, 2008 – March 31, 2011), and has concluded that no provision for federal income tax is required in the Funds’ financial statements.

Interest and Related Expenses — Interest and related expenses include, but are not limited to, interest expense, remarketing fees, liquidity fees, and trustees’ fees from the Funds’ participation in inverse floater programs where a Fund has transferred its own bonds to a trust that issues floating rate securities with an aggregate principal amount equal to the principal of the transferred bonds. In conveyance of the bond, the Funds receive the inverse floating rate securities and cash from the trust. As a result of certain rights retained by the Funds, the transfer of the bond is not considered a sale, but rather a form of financing for accounting purposes whereby the cash received is recorded as a liability and interest expense is recorded based on the interest rate of the floating rate securities. Remarketing fees, liquidity fees, and trustees’ expenses are recorded on the accrual basis. There were no interest and related expenses for the year ended March 31, 2011.

Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the differences could be material.

Other — Expenses directly attributable to a Fund are charged directly to that Fund. Other expenses common to various funds within the Delaware Investments® Family of Funds are generally allocated amongst such funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Interest income is recorded on the accrual basis. Discounts and premiums are amortized to interest income over the lives of the respective securities. Each Fund declares and pays dividends from net investment income monthly and distributions from net realized gain on investments, if any, annually. Each Fund may distribute income dividends and capital gains more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on ex-dividend date.

The Funds may receive earnings credits from their custodian when positive cash balances are maintained, which are used to offset custody fees. There were no earnings credits for the year ended March 31, 2011.

The Funds may receive earnings credits from their transfer agent when positive cash balances are maintained, which are used to offset transfer agent fees. There were no earnings credits for the year ended March 31, 2011.

2. Investment Management, Administration Agreements and Other Transactions with Affiliates

In accordance with the terms of its respective investment management agreement, each Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the investment manager, an annual fee of 0.40% which is calculated daily based on the adjusted average daily net assets of each Fund.

The fees payable to DSC under the service agreement described above are allocated among all Funds in the Delaware Investments Family of Funds on a relative net asset value basis. For the year ended March 31, 2011, the Funds were charged as follows:

Arizona	Colorado	Minnesota	National
Municipal	Municipal	Municipal	Municipal
Fund	Fund	Fund II	Fund
$2,056	$3,358	$8,051	$1,587

Net unrealized appreciation (depreciation)		$	(1,393,450	)		$	(2,043,064	)		$	855,632			$	(333,914	)

U.S. GAAP defines fair value as the price that the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. Each Fund’s investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three level hierarchy of inputs is summarized below.

Level 1 –	inputs are quoted prices in active markets for identical investments (e.g., equity securities, open-end investment companies, futures contracts, options contracts)

Level 2 –	other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs) (e.g., debt securities, government securities, swap contracts, foreign currency exchange contracts, foreign securities utilizing international fair value pricing)

Level 3 –	inputs are significant unobservable inputs (including the Fund’s own assumptions used to determine the fair value of investments) (e.g., broker-quoted securities, fair valued securities)

The following table summarizes the valuation of each Fund’s investments by fair value hierarchy levels as of March 31, 2011:

	Arizona Municipal Fund
		Level 2
Municipal Bonds		$	37,279,422
Short-Term Investments			1,800,000
Total		$	39,079,422

	Colorado Municipal Fund
		Level 2
Municipal Bonds		$	61,424,917
Short-Term Investments			2,300,000
Total		$	63,724,917

	Minnesota Municipal Fund II
		Level 2
Municipal Bonds		$	155,404,752
Short-Term Investments			900,000
Total		$	156,304,752

	National Municipal Fund
		Level 2
Municipal Bonds		$	28,746,822
Short-Term Investments			1,400,000
Total		$	30,146,822

There were no unobservable (Level 3) investments at the beginning or end of the year.

During the year ended March 31, 2011, there were no transfers between Level 1 investments, Level 2 investments or Level 3 investments that had a material impact to the Funds.

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Additionally, distributions from net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended March 31, 2011 and 2010 was as follows:

	Arizona			Colorado			Minnesota			National
	Municipal			Municipal			Municipal			Municipal
	Fund			Fund			Fund II			Fund
Year Ended 3/31/11
Ordinary income		$	29,445		$	—		$	395		$	24,594
Tax-exempt income			1,544,246			2,757,147			6,557,441			1,253,117

Total		$	1,513,467		$	2,757,147		$	6,557,836		$	1,235,322

5. Components of Net Assets on a Tax Basis

As of March 31, 2011, the components of net assets on a tax basis were as follows:

	Arizona			Colorado			Minnesota			National
	Municipal			Municipal			Municipal			Municipal
	Fund			Fund			Fund II			Fund
Shares of beneficial interest		$40,651,205			$66,918,121			$157,931,075			$33,208,317
Undistributed long-term capital gains		64,325			—			—			—
Undistributed tax-exempt income		461,800			323,399			827,677			344,090
Capital loss carryforwards		—			(509,083	)		(1,959,315	)		(2,494,617	)
Post-October losses		—			—			—			(165,114	)
Unrealized appreciation (depreciation) of investments		(1,393,450	)		(2,043,064	)		855,632			(333,914	)
Net assets		$39,783,880			$64,689,373			$157,655,069			$30,558,762

The differences between book basis and tax basis components of net assets are primarily attributable to tax treatment of market discount on debt instruments.

Post-October losses represent losses realized on investment transactions from November 1, 2010 through March 31, 2011 that, in accordance with federal income tax regulations, the Funds have elected to defer and treat as having arisen in the following fiscal year.

For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of market discount on debt instruments. Results of operations and net assets were not affected by these reclassifications. For the year ended March 31, 2011, the Funds recorded the following reclassifications.

	Arizona			Colorado			Minnesota			National
	Municipal			Municipal			Municipal			Municipal
	Fund			Fund			Fund II			Fund
Undistributed net investment income		$ 23,530			$(3,795	)		$(16,279	)		$(1,673	)
Accumulated net realized gain (loss)		(23,530	)		3,795			16,279			1,673

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. $163,835, $298,574, and $154,758 was utilized in 2011 for Colorado Municipal Fund, Minnesota Municipal Fund II and National Municipal Fund, respectively. Capital loss carryforwards remaining at March 31, 2011 will expire as follows:

	Colorado		Minnesota		National
	Municipal		Municipal		Municipal
Year of Expiration	Fund		Fund II		Fund
2017		$509,083		$1,695,121		$1,634,822
2018		—		264,194		859,795
Total		$509,083		$1,959,315		$2,494,617

6. Capital Stock

Pursuant to their articles of incorporation, Arizona Municipal Fund, Colorado Municipal Fund and Minnesota Municipal Fund II each have 200 million shares of $0.01 par value common shares authorized. National Municipal Fund has been authorized to issue an unlimited amount of $0.01 par value common shares. The Funds did not repurchase any shares under the Share Repurchase Program during the year ended March 31, 2011. Shares issuable under the Funds’ dividend reinvestment plan are purchased by the Funds’ transfer agent, BNY Mellon Shareowner Services, in the open market.

For the year ended March 31, 2011, the Funds did not have any transactions in common shares.

7. Derivatives

U.S. GAAP requires enhanced disclosures that enable investors to understand: 1) how and why an entity uses derivatives; 2) how they are accounted for; and 3) how they affect an entity’s results of operations and financial position.

Inverse Floaters — Each Fund may participate in inverse floater programs where a fund transfers its own bonds to a trust that issues floating rate securities and inverse floating rate securities (inverse floaters) with an aggregate principal amount equal to the principal of the transferred bonds. The inverse floaters received by the Funds are derivative tax-exempt obligations with floating or variable interest rates that move in the opposite direction of short-term interest rates, usually at an accelerated speed. Consequently, the market values of the inverse floaters will generally be more volatile than other tax-exempt investments. The Funds typically use inverse floaters to adjust the duration of their portfolio. Duration measures a portfolio’s sensitivity to changes in interest rates. By holding inverse floaters with a different duration than the underlying bonds that a Fund transferred to the trust, the Fund seeks to adjust its portfolio’s sensitivity to changes in interest rates. The Funds may also invest in inverse floaters to add additional income to the Funds or to adjust the Funds’ exposure to a specific segment of the yield curve. At March 31, 2011, and during the year then ended, the Funds held no investments in inverse floaters.

8. Credit and Market Risk

The Funds concentrate their investments in securities issued by municipalities. The value of these investments may be adversely affected by new legislation within the states, regional or local and national economic conditions, as applicable and differing levels of supply and demand for municipal bonds. Many municipalities insure repayment for their obligations. Although bond insurance reduces the risk of loss due to default by an issuer, such bonds remain subject to the risk that market value may fluctuate for other reasons and there is no assurance that the insurance company will meet its obligations. A real or perceived decline in creditworthiness of a bond insurer can have an adverse impact on the value of insured bonds held in each Fund. At March 31, 2011, the percentages of each Fund’s net assets insured by insurers are listed below and these securities have been identified in the statements of net assets.

Arizona Municipal Fund	32%
Colorado Municipal Fund	39%
Minnesota Municipal Fund II	21%
National Municipal Fund	25%

The Funds invest a portion of their assets in high yield fixed income securities, which carry ratings of BB or lower by Standard & Poor’s Rating Group (S&P) and/or Ba or lower by Moody’s Investors Service, Inc. (Moody’s). Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities.

The Funds may invest in advanced refunded bonds, escrow secured bonds or defeased bonds. Under current federal tax laws and regulations, state and local government borrowers are permitted to refinance outstanding bonds by issuing new bonds. The issuer refinances the outstanding debt to either reduce interest costs or to remove or alter restrictive covenants imposed by the bonds being refinanced. A refunding transaction where the municipal securities are being refunded within 90 days from the issuance of the refunding issue is known as a “current refunding.” “Advance refunded bonds” are bonds in which the refunded bond issue remains outstanding for more than 90 days following the issuance of the refunding issue. In an advance refunding, the issuer will use the proceeds of a new bond issue to purchase high grade interest bearing debt securities which are then deposited in an irrevocable escrow account held by an escrow agent to secure all future payments of principal and interest and bond premium of the advance refunded bond. Bonds are “escrowed to maturity” when the proceeds of the refunding issue are deposited in an escrow account for investment sufficient to pay all of the principal and interest on the original interest payment and maturity dates.

Bonds are considered “pre-refunded” when the refunding issue’s proceeds are escrowed only until a permitted call date or dates on the refunded issue with the refunded issue being redeemed at the time, including any required premium. Bonds become “defeased” when the rights and interests of the bondholders and of their lien on the pledged revenues or other security under the terms of the bond contract are substituted with an alternative source of revenues (the escrow securities) sufficient to meet payments of principal and interest to maturity or to the first call dates. Escrowed secured bonds will often receive a rating of AAA from Moody’s, S&P, and/or Fitch Ratings due to the strong credit quality of the escrow securities and the irrevocable nature of the escrow deposit agreement.

8. Credit and Market Risk (continued)

Each Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, each Fund’s Board has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of each Fund’s limitation on investments in illiquid assets. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Funds’ 15% limit on investments in illiquid securities. As of March 31, 2011, there were no Rule 144A securities and no securities have been determined to be illiquid under the Funds’ Liquidity Procedures.

9. Contractual Obligations

The Funds enters into contracts in the normal course of business that contain a variety of indemnifications. The Funds’ maximum exposure under these arrangements is unknown. However, the Funds have not had prior claims or losses pursuant to these contracts. Management has reviewed each Fund’s existing contracts and expects the risk of loss to be remote.

10. Investments in Municipal Securities Issued by the State of Florida

On September 13, 2007, shareholders of Delaware Investments National Municipal Income Fund (formerly Delaware Investments Florida Insured Municipal Income Fund) approved (1) the elimination of the Fund’s fundamental investment policy that required the Fund to invest primarily in insured municipal securities issued by the State of Florida and (2) the adoption of a new fundamental investment policy permitting the Fund to invest in un-insured municipal securities issued by states other than Florida. The Fund’s portfolio managers began to transition the Fund’s portfolio to include un-insured municipal bonds issued by other states and territories on October 15, 2007. As of March 31, 2011, municipal bonds issued by the state of Florida constitute approximately 23% of the Fund’s portfolio. These investments could make the Fund more sensitive to economic conditions in Florida than other more geographically diversified national municipal income funds.

11. Proposed Reorganization

On November 19, 2010, the Boards of Directors/Trustees of the National Municipal Fund (NYSE Amex: VFL) and the Arizona Municipal Fund (NYSE Amex: VAZ) announced their approval of the reorganization of the Arizona Municipal Fund into the National Municipal Fund. Under the terms of the proposed reorganization, the National Municipal Fund would acquire substantially all of the Arizona Municipal Fund’s assets in exchange for newly issued shares of beneficial interest of the National Municipal Fund. Those shares of the National Municipal Fund would then be distributed pro rata to Arizona Municipal Fund’s shareholders, and the Arizona Municipal Fund would subsequently be liquidated and dissolved. Common shares of Arizona Municipal Fund would be exchanged for common shares of National Municipal Fund based on the relative net asset values of each Fund’s common shares. These transactions, which are expected to be tax-free, are subject to the approval of the Agreement and Plan of Acquisition by each Fund’s shareholders (which includes the National Municipal Fund’s approval of the issuance of new common shares). The Funds’ joint special shareholders meeting to consider the reorganization is now scheduled to take place on May 23, 2011.

In addition, on February 18, 2011, the Board of Trustees of the National Municipal Fund announced its decision to conduct a tender offer after shareholder approval and completion of the reorganization of Arizona Municipal Fund into the National Municipal Fund. Under the terms of the proposed tender offer, the National Municipal Fund would offer to purchase for cash up to 18% of the then-outstanding shares of the National Municipal Fund’s common stock after the reorganization (Common Stock) at a per share price equal to 99% of the net asset value per share of the Common Stock at the expiration of the tender offer. It is currently anticipated that the tender offer would commence within three months after the closing date of the reorganization of Arizona Municipal Fund into the National Municipal Fund. Please refer to the Funds’ press release for more information.

12. Subsequent Events

Management has determined no material events or transactions, other than the proposed reorganization, occurred subsequent to March 31, 2011 that would require recognition or disclosure in the Funds’ financial statements.

13. Tax Information (Unaudited)

The information set forth below is for each Fund’s fiscal year as required by federal income tax laws. Shareholders, however, must report distributions on a calendar year basis for income tax purposes, which may include distributions for portions of two fiscal years of a fund. Accordingly, the information needed by shareholders for income tax purposes will be sent to them in January of each year. Please consult your tax advisor for proper treatment of this information.

For the fiscal year ended March 31, 2011, each Fund designates distributions paid during the year as follows:

	(A)		(B)			(C)
	Ordinary		Tax-Exempt			Long-Term
	Income		Income			Capital Gain		Total
	Distributions		Distributions			Distributions		Distributions
	(Tax Basis)		(Tax Basis)			(Tax Basis)		(Tax Basis)
Arizona Municipal Fund		1.73%		90.77	%		7.50%	100.00%

Minnesota Municipal Fund II		0.01%		99.99	%		—	100.00%
National Municipal Fund		1.92%		98.08	%		—	100.00%

(A), (B), and (C) are based on a percentage of each Fund’s total distributions.

In our opinion, the accompanying statements of net assets and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Delaware Investments Arizona Municipal Income Fund, Inc., Delaware Investments Colorado Municipal Income Fund, Inc., Delaware Investments Minnesota Municipal Income Fund II, Inc. and Delaware Investments National Municipal Income Fund (the “Funds”) at March 31, 2011, and the results of its operations, the changes in its net assets and the financial highlights for the year then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2011 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The statement of changes in net assets for the year ended March 31, 2010 and the financial highlights for each of the four years in the period ended March 31, 2010 were audited by other independent accountants whose report dated May 19, 2010 expressed an unqualified opinion on those statements.

Dividend Reinvestment Plan

Each Fund offers an automatic dividend reinvestment program (“Plan”). Under the current policies of Arizona Municipal Income Fund, Minnesota Municipal Income Fund II, and National Municipal Income Fund all distributions of net investment income and capital gains to common shareholders are automatically reinvested in additional shares unless shareholders elect to receive all dividends and other distributions in cash paid by check mailed directly to shareholders by the dividend plan agent. Under the current policies of Colorado Municipal Income Fund, distributions of net investment income and capital gains to common shareholders will be paid in cash unless shareholders notify BNY Mellon Investor Services, Inc. (“BNY Mellon”) of their desire to participate in the dividend reinvestment program. Shareholders who hold their shares through a bank, broker or other nominee should request the bank, broker or nominee to participate in the Plan on their behalf. This can be done as long as the bank, broker or nominee provides a dividend reinvestment service for the Funds. If the bank, broker or nominee does not provide this service, such shareholders must have their shares taken out of “street” or nominee name and re-registered in their own name in order to participate in the Plan.

BNY Mellon will apply all cash dividends, capital gains and other distributions (collectively, “Distributions”) on each Fund’s shares of common stock which become payable to each Plan participant to the purchase of outstanding shares of each Fund’s common stock for such participant. These purchases may be made on a securities exchange or in the over-the-counter market, and may be subject to such terms of price, delivery and related matters to which BNY Mellon may agree. The Funds will not issue new shares in connection with the Plan.

Distributions reinvested for participants are subject to income taxes just as if they had been paid directly to the shareholder in cash. Participants will receive a year-end statement showing distributions reinvested, and any brokerage commissions paid on such participant’s behalf.

Shareholders holding shares of a Fund in their own names who wish to terminate their participation in the Plan may do so by sending written instruction to BNY Mellon so that BNY Mellon receives such instructions at least 10 days prior to the Distribution record date. Shareholders with shares held in account by a bank, broker or other nominee should contact such bank, broker or other nominee to determine the procedure for withdrawal from the Plan.

If written instructions are not received by BNY Mellon at least 10 days prior to the record date for a particular Distribution, that Distribution may be reinvested at the sole discretion of BNY Mellon. After a shareholder’s instructions to terminate participation in the Plan become effective, Distributions will be paid to shareholders in cash. Upon termination, a shareholder may elect to receive either stock or cash for all the full shares in the account. If cash is elected, BNY Mellon will sell such shares at the then current market value and then send the net proceeds to the shareholder, after deducting brokerage commissions and related expenses. Any fractional shares at the time of termination will be paid in cash at the current market price, less brokerage commissions and related expenses, if any. Shareholders may at any time request a full or partial withdrawal of shares from the Plan, without terminating participation in the Plan. When shares outside of the Plan are liquidated, Distributions on shares held under the Plan will continue to be reinvested unless BNY Mellon is notified of the shareholder’s withdrawal from the Plan.

An investor holding shares that participate in the Plan in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. Please contact your broker/dealer for additional details.

BNY Mellon will charge participants their proportional share of brokerage commissions on market purchases. Participants may obtain a certificate or certificates for all or part of the full shares credited to their accounts at any time by making a request in writing to BNY Mellon. A fee may be charged to the participant for each certificate issuance.

If you have any questions and shares are registered in “street” name, contact the broker/dealer holding the shares or your financial advisor. If you have any questions and shares are registered in your name, contact BNY Mellon at 800 851-9677.

Change in Independent Registered Public Accounting Firm

Due to independence matters under the Securities and Exchange Commission’s auditor independence rules relating to the January 4, 2010 acquisition of Delaware Investments (including DMC, DDLP and DSC) by Macquarie Group, Ernst & Young LLP (E&Y) has resigned as the independent registered public accounting firm for Delaware Investments Arizona Municipal Income Fund, Inc., Delaware Investments Colorado Municipal Income Fund, Inc., Delaware Investments Minnesota Municipal Income Fund II, Inc., and Delaware Investments National Municipal Income Fund (the Funds) effective May 27, 2010. At a meeting held on February 18, 2010, the Board of Directors/Trustees of the Funds, upon recommendation of the Audit Committee, selected PricewaterhouseCoopers LLC (PwC) to serve as the independent registered public accounting firm for the Funds for the fiscal year ending March 31, 2011. During the fiscal years ended March 31, 2009 and March 31, 2010, E&Y’s audit reports on the financial statements of the Funds did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. In addition, there were no disagreements between the Funds and E&Y on accounting principles, financial statements disclosures or audit scope, which, if not resolved to the satisfaction of E&Y, would have caused them to make reference to the disagreement in their reports. None of the Funds nor anyone on their behalf has consulted with PwC at any time prior to their selection with respect to the application of accounting principles to a specified transaction, either completed or proposed or the type of audit opinion that might be rendered on the Funds’ financial statements.

The Pre-Approval Policy requires the registrant’s independent auditors to report to the Audit Committee at each of its regular meetings regarding all services initiated since the last such report was rendered, including those services authorized by the Pre-Approval Policy.

(f) Not applicable.

(g) The aggregate non-audit fees billed by the registrant’s independent auditors for services rendered to the registrant and to its investment adviser and other service providers under common control with the adviser were $25,000 and $204,564 for the registrant’s fiscal years ended March 31, 2011 and March 31, 2010, respectively.

(h) In connection with its selection of the independent auditors, the registrant’s Audit Committee has considered the independent auditors’ provision of non-audit services to the registrant’s investment adviser and other service providers under common control with the adviser that were not required to be pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X. The Audit Committee has determined that the independent auditors’ provision of these services is compatible with maintaining the auditors’ independence.

Item 5. Audit Committee of Listed Registrants

The registrant has a separately-designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934. The members of the registrant’s Audit Committee are John A. Fry, Thomas F. Madison and Janet L. Yeomans.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

The registrant has formally delegated to its investment adviser(s) (the “Adviser”) the ability to make all proxy voting decisions in relation to portfolio securities held by the registrant. If and when proxies need to be voted on behalf of the registrant, the Adviser will vote such proxies pursuant to its Proxy Voting Policies and Procedures (the “Procedures”). The Adviser has established a Proxy Voting Committee (the “Committee”) which is responsible for overseeing the Adviser’s proxy voting process for the registrant. One of the main responsibilities of the Committee is to review and approve the Procedures to ensure that the Procedures are designed to allow the Adviser to vote proxies in a manner consistent with the goal of voting in the best interests of the registrant.

In order to facilitate the actual process of voting proxies, the Adviser has contracted with Institutional Shareholder Services (“ISS”), a subsidiary of RiskMetrics Group (“RiskMetrics”), which is a subsidiary of MSCI Inc., to analyze proxy statements on behalf of the registrant and other Adviser clients and vote proxies generally in accordance with the Procedures. The Committee is responsible for overseeing ISS/RiskMetrics’s proxy voting activities. If a proxy has been voted for the registrant, ISS/RiskMetrics will create a record of the vote. By no later than August 31 of each year, information (if any) regarding how the registrant voted proxies relating to portfolio securities during the most recently disclosed 12-month period ended June 30 is available without charge (i) through the registrant’s website at http://www.delawareinvestments.com; and (ii) on the Commission’s website at http://www.sec.gov.

The Procedures contain a general guideline that recommendations of company management on an issue (particularly routine issues) should be given a fair amount of weight in determining how proxy issues should be voted. However, the Adviser will normally vote against management’s position when it runs counter to its specific Proxy Voting Guidelines (the “Guidelines”), and the Adviser will also vote against management’s recommendation when it believes that such position is not in the best interests of the registrant.

As stated above, the Procedures also list specific Guidelines on how to vote proxies on behalf of the registrant. Some examples of the Guidelines are as follows: (i) generally vote for shareholder proposals asking that a majority or more of directors be independent; (ii) generally vote against proposals to require a supermajority shareholder vote; (iii) votes on mergers and acquisitions should be considered on a case-by-case basis, determining whether the transaction enhances shareholder value; (iv) generally vote against proposals to create a new class of common stock with superior voting rights; (v) generally vote re-incorporation proposals on a case-by-case basis; (vi) votes with respect to equity-based compensation plans are generally determined on a case-by-case basis; and (vii) generally vote for proposals requesting reports on the level of greenhouse gas emissions from a company’s operations and products.

Because the registrant has delegated proxy voting to the Adviser, the registrant is not expected to encounter any conflict of interest issues regarding proxy voting and therefore does not have procedures regarding this matter. However, the Adviser does have a section in its Procedures that addresses the possibility of conflicts of interest. Most proxies which the Adviser receives on behalf of the registrant are voted by ISS/RiskMetrics in accordance with the Procedures. Because almost all registrant proxies are voted by ISS/RiskMetrics pursuant to the pre-determined Procedures, it normally will not be necessary for the Adviser to make an actual determination of how to vote a particular proxy, thereby largely eliminating conflicts of interest for the Adviser during the proxy voting process. In the very limited instances where the Adviser is considering voting a proxy contrary to ISS/RiskMetrics’s recommendation, the Committee will first assess the issue to see if there is any possible conflict of interest involving the Adviser or affiliated persons of the Adviser. If a member of the Committee has actual knowledge of a conflict of interest, the Committee will normally use another independent third party to do additional research on the particular proxy issue in order to make a recommendation to the Committee on how to vote the proxy in the best interests of the registrant. The Committee will then review the proxy voting materials and recommendation provided by ISS/RiskMetrics and the independent third party to determine how to vote the issue in a manner which the Committee believes is consistent with the Procedures and in the best interests of the registrant.

DESCRIPTION OF MATERIAL CONFLICTS OF INTEREST

Individual portfolio managers may perform investment management services for other funds or accounts similar to those provided to the Funds and the investment action for such other fund or account and the Funds may differ. For example, an account or fund may be selling a security, while another account or Fund may be purchasing or holding the same security. As a result, transactions executed for one fund or account may adversely affect the value of securities held by another fund, account or Fund. Additionally, the management of multiple other funds or accounts and the Funds may give rise to potential conflicts of interest, as a portfolio manager must allocate time and effort to multiple funds or accounts and the Funds. A portfolio manager may discover an investment opportunity that may be suitable for more than one account or fund. The investment opportunity may be limited, however, so that all funds or accounts for which the investment would be suitable may not be able to participate. The Manager has adopted procedures designed to allocate investments fairly across multiple funds or accounts.

A portfolio manager’s management of personal accounts also may present certain conflicts of interest. While Delaware’s code of ethics is designed to address these potential conflicts, there is no guarantee that it will do so.

Compensation Structure
Each portfolio’s manager’s compensation consists of the following:

Base Salary - Each named portfolio manager receives a fixed base salary. Salaries are determined by a comparison to industry data prepared by third parties to ensure that portfolio manager salaries are in line with salaries paid at peer investment advisory firms.

Bonus - An objective component is added to the bonus for each manager that is reflective of account performance relative to an appropriate peer group or database. The following paragraph describes the structure of the non-guaranteed bonus.

Each portfolio manager is eligible to receive an annual cash bonus, which is based on quantitative and qualitative factors. There is one pool for bonus payments for the fixed income department. The amount of the pool for bonus payments is determined by assets managed (including investment companies, insurance product-related accounts and other separate accounts), management fees and related expenses (including fund waiver expenses) for registered investment companies, pooled vehicles, and managed separate accounts. Generally, 60%-75% of the bonus is quantitatively determined. For more senior portfolio managers, a higher percentage of the bonus is quantitatively determined. For investment companies, each manager is compensated according the Fund’s Lipper or Morningstar peer group percentile ranking on a one-year, three-year, and five-year basis, with longer-term performance more heavily weighted. For managed separate accounts the portfolio managers are compensated according to the composite percentile ranking against the Frank Russell and Callan Associates databases (or similar sources of relative performance data) on a one-year, three-year, and five-year basis, with longer term performance more heavily weighted. There is no objective award for a fund that falls below the 50th percentile, but incentives reach maximum potential at the 25th-30th percentile. There is a sliding scale for investment companies that are ranked above the 50th percentile. The remaining 25%-40% portion of the bonus is discretionary as determined by Delaware Investments and takes into account subjective factors.

For new and recently transitioned portfolio managers, the compensation may be weighted more heavily towards a portfolio manager’s actual contribution and ability to influence performance, rather than longer-term performance. Management intends to move the compensation structure towards longer-term performance for these portfolio managers over time.

Incentive Plan/Equity Compensation Plan - Portfolio managers may be awarded options, stock appreciation rights, restricted stock awards, restricted stock units, deferred stock units, and performance awards (collectively, “Awards”) relating to the underlying shares of common stock of Delaware Investments U.S., Inc. pursuant to the terms of the Delaware Investments U.S., Inc. 2009 Incentive Compensation Plan (the “Plan”) established on March 24, 2009. Since the establishment of the Plan, Awards are no longer granted under the Amended and Restated Delaware Investments U.S., Inc. Incentive Compensation Plan effective December 26, 2008, which was established in 2001.

�� The Plan was established in order to: assist the Manager in attracting, retaining, and rewarding key employees of the company; enable such employees to acquire or increase an equity interest in the company in order to align the interest of such employees and the Manager; and provide such employees with incentives to expend their maximum efforts. Subject to the terms of the Plan and applicable award agreements, Awards typically vest in 25% increments on a four-year schedule, and shares of common stock underlying the Awards are issued after vesting. Shares issued typically must be held for six months and one day, after which time the stockholder may put them back to the company, subject to any applicable holding requirements. The fair market value of the shares of Delaware Investments U.S., Inc., is normally determined as of each March 31, June 30, September 30 and December 31. The fair market value of shares of common stock underlying Awards granted on or after December 26, 2008 is determined by an independent appraiser utilizing an appraisal valuation methodology in compliance with Section 409A of the Internal Revenue Code and the regulations promulgated thereunder.

Other Compensation - Portfolio managers may also participate in benefit plans and programs available generally to all employees.

As of May 13, 2011, the portfolio managers of the Fund did not own any Fund shares.
